My gateway is not connecting

You´ve got a second NIC with IP 10.42.0.1 why is this?

That is something internal to gateway . It will help you know that it is connected

Do you have checked the NTP Service is linked to the VM? 

@Sophos User5771 where to you put the configuration of the 2nd NIC to ztna-gateway config as I know within in the setup process you can give only one IP Adress to zntn-gateway config?

@LuCar Toni you mean within ESXi?

That IP will be automatically configured by the gateway . We specify only one IP when we setup the gateway. 

Updating this thread. Thanks, Matthias for your time. We had a debug session and the issue has been resolved and the gateway is managed. The issue was with an upstream firewall rule allowing traffic to AWS. Please feel free to reach out in case you need any help.
